The HERMA glow-in-the-dark stickers or wall decals can be removed without leaving any residue from smooth, dirt-, moisture-, and grease-free surfaces, making them suitable for changing decorations in children's bedrooms and playrooms. They absorb incoming light and release it in the dark, allowing them to glow for a long time. The cheerful, fluorescent stickers can be easily applied to light switches, in children's rooms, on ceilings, and walls, creating a delightful starry sky, for example. Delight your little guests at birthday parties with the glow stickers as party favors. They are also perfect for school enrollment, school cones, or as a wonderful surprise in an Advent calendar.
